template:
  - sensor:
      - name: "Epex Spot template price sensor"
        unique_id: epex_spot_template_price_sensor
        unit_of_measurement: "€/kWh"
        state: "{{ states('sensor.epex_spot_data_net_price') }}"
        availability: "{{ 'sensor.epex_spot_data_net_price' | has_value }}"
        attributes:
            prices_today: >
                {%- set forecast_data = state_attr('sensor.epex_spot_data_net_price', 'data') %}
